+ * The Host writes BMI requests to mailbox0, and reads BMI responses
+ * from mailbox0. BMI requests all begin with a command

This looks exactly like ath6kl, but is it? Seems it might have potential
for sharing the code.

Somewhere deep down ath10k and ath6kl have common history, but the
firmware engineers have made so many changes everywhere that IMHO trying
to share code is not really worth it.

+/*
+ * A single CopyEngine (CE) comprises two "rings":
+ * a source ring
+ * a destination ring
+ *
+ * Each ring consists of a number of descriptors which specify
+ * an address, length, and meta-data.
+ *
+ * Typically, one side of the PCIe interconnect (Host or Target)
+ * controls one ring and the other side controls the other ring.
+ * The source side chooses when to initiate a transfer and it
+ * chooses what to send (buffer address, length). The destination
+ * side keeps a supply of "anonymous receive buffers" available and
+ * it handles incoming data as it arrives (when the destination
+ * recieves an interrupt).
+ *
+ * The sender may send a simple buffer (address/length) or it may
+ * send a small list of buffers. When a small list is sent, hardware
+ * "gathers" these and they end up in a single destination buffer
+ * with a single interrupt.
+ *
+ * There are several "contexts" managed by this layer -- more, it
+ * may seem -- than should be needed. These are provided mainly for
+ * maximum flexibility and especially to facilitate a simpler HIF
+ * implementation. There are per-CopyEngine recv, send, and watermark
+ * contexts. These are supplied by the caller when a recv, send,
+ * or watermark handler is established and they are echoed back to
+ * the caller when the respective callbacks are invoked. There is
+ * also a per-transfer context supplied by the caller when a buffer
+ * (or sendlist) is sent and when a buffer is enqueued for recv.
+ * These per-transfer contexts are echoed back to the caller when
+ * the buffer is sent/received.

+ * This file specifies the WMI interface for the Unified Software
+ * Architecture.
+ *
+ * It includes definitions of all the commands and events. Commands are
+ * messages from the host to the target. Events and Replies are messages
+ * from the target to the host.
+ *
+ * Ownership of correctness in regards to WMI commands belongs to the host
+ * driver and the target is not required to validate parameters for value,
+ * proper range, or any other checking.
+ *
+ * Guidelines for extending this interface are below.
+ *
+ * 1. Add new WMI commands ONLY within the specified range - 0x9000 - 0x9fff
+ *
+ * 2. Use ONLY u32 type for defining member variables within WMI
+ * command/event structures. Do not use u8, u16, bool or
+ * enum types within these structures.
+ *
+ * 3. DO NOT define bit fields within structures. Implement bit fields
+ * using masks if necessary. Do not use the programming language's bit
+ * field definition.
+ *
+ * 4. Define macros for encode/decode of u8, u16 fields within
+ * the u32 variables. Use these macros for set/get of these fields.
+ * Try to use this to optimize the structure without bloating it with
+ * u32 variables for every lower sized field.
+ *
+ * 5. Do not use PACK/UNPACK attributes for the structures as each member
+ * variable is already 4-byte aligned by virtue of being a u32
+ * type.
+ *
+ * 6. Comment each parameter part of the WMI command/event structure by
+ * using the 2 stars at the begining of C comment instead of one star to
+ * enable HTML document generation using Doxygen.

Perhaps it would be reasonable to create and use standardized
logging ath_<level> functions for all the device ath<x>k_<level>s.

Indeed.
You already did that in "ath: Add and use ath_printk and ath_<level>" :)

IIRC Sujith actually suggested this to me already earlier, but I didn't
buy the idea even then. ath9k and ath10k are very different, so we
cannot share all the debug levels. I just feel that it restricts and
confuses the driver debugging too much, and all just to save something
like 100 lines of code. I'm having hard time to see why bother.

I also noticed that ath.h doesn't support tracing. I would hate to lose
that.
